METHOD TO DETERMINE INCREASED IN AIRCRAFT LIFT AT EXTERNAL POWER FEED Russian patent published in 2013 - IPC G01M9/00

Abstract RU 2488796 C1

FIELD: aircraft engineering.

SUBSTANCE: proposed method comprises making aircraft model and its weight testing in wind tunnel. To define the increase in aircraft lift at external power feed by tests of its model in wind tunnel geometrical similarity of the model with aircraft and power feed point is a must. Note here that external power carrier represents inert gas, for example, helium with high specific static enthalpy. Model lift increase in wind tunnel is measured at external power feed to define similarity factor so that lift increase for natural aircraft is determined.

EFFECT: determination of increase in aircraft lift by using its model in wind tunnel.
